What is Camelis ?

This software is an implementation of Logical Information Systems (LIS).

A LIS allows to automatically organize data given an indexation of objects by logical properties, and to combine boolean querying and non-hierarchical navigation when searching information.

It is developped by Sébastien Ferré in project LIS at Irisa.

How does it work ?

LIS are based on Concept Analysis, which provide a formal way to organize object-centered data in a concept lattice.

This lattice acts as a navigation space where each concept is a navigation place, and any object can be in any number of places. These places are reached by following navigation links that are automatically computed from original data.

A logical generalization of concept analysis is use so that expressive formulas can be used to describe objects, formulate queries, and represent navigation links.
